Consider the following statements and select the correct option which correctly identifies true (T) and false (F).

Question 1

(i) Magnetic field lines do not intersect because they always travel parallel to each other in North to South direction.

(ii) When a current flows through a straight copper conductor, it gets permanently magnetised.

(iii) The strength of magnetic field at the centre of a circular coil is inversely proportional to the radius of coil.

Question 2

Correct option (C)

Explanation:

(i)The magnetic field lines do not intersect, if they did, the direction of magnetic field would not be unique at the point of intersection.

(ii) Copper conductor acts as a magnet as long as current flows through it.

(iii) Magnetic field at the centre of circular coil is
